          """Return a dict that can be JSONify using json.dump.
  
          Advanced usage might optionaly use a callback as parameter:

                  return key
  
          Key is the attribute name used in Python. Attr_desc
          is a dict of metadata. Currently contains 'type' with the
          msrest type and 'key' with the RestAPI encoded key.
          Value is the current value in this object.
  
          The string returned will be used to serialize the key.
          If the return type is a list, this is considered hierarchical
          result dict.
  
          See the three examples in this file:
